Definitions

  • a system as defined in the preamble of claim 1 and a method as defined in the preamble of claim 12 is known from US 2002/0168937 A1 .
  • the system facilitates wireless communication between nodes of a welding cell.
  • US 2008/0011727 A1 discloses a method for synchronizing two welding devices. It comprises two identical welding machines which are synchronized to perform simultaneously identical actions with identical welding parameter settings to reach identical welds.
  • a power supply is generally coupled to a wire feeder that provides a controlled supply of welding wire electrode through a welding gun.
  • the power supply or wire feeder is also typically coupled to a supply of shielding gas.
  • the power us ultimately supplied to a welding gun or torch, used to complete the electrical circuit for the welding arc.
  • the present invention provides a novel approach to welding system control designed to respond to such needs.
  • the approach is based upon synchronization of operations of welding components, thereby leading to more determinative control in which certain operations can be scheduled rather than performed based on feedback of sensed parameters.
  • the system may, and typically will, make use of parameter sensing and feedback, followed by computations and closed loop control, as in conventional welding systems, but the ability to schedule events by virtue of the proposed synchronization may greatly facilitate the performance of many tasks in the welding operation. These may be performed by the different synchronized components, scheduled to operate in parallel, with tasks and closed loop control being advanced following certain scheduled operations as is defined in claims 1 and 12. It is believed that many options and future innovations may flow from the synchronization of the welding system components, particularly once these are freed, at least somewhat, from reactive-only closed loop control.
  • MIG welding system is illustrated in FIG. 1
  • the present techniques may be employed with any welding system, welding process, and welding component.
  • TIG systems, stick systems, and so forth may utilize similar techniques based upon the present disclosure.
  • processes may include constant current processes, constant voltage processes, pulse processes, and so forth, and a number of different material transfer modes may be accommodated, such as short circuit transfer, spray transfer, globular transfer, and so forth.
  • the welding power supply 12 comprises arc control circuitry 20 coupled to gate drive circuitry 22.
  • the arc control circuitry is designed to control a welding arc established between the welding electrode and the work piece, particularly based upon the synchronized and coordinated control described in the present discussion.
  • the arc control circuitry may be part of a controller that performs a number of other functions in the power supply and the welding system.
  • the arc control circuitry will typically include a microprocessor or digital signal processor and associated memory.
  • the memory stores pre-defined welding processes, welding parameters, weld settings, and so forth utilized by the arc control circuitry throughout the welding processes.
  • the gate drive circuitry 22 receives signals from the arc control circuitry to regulate conductive states of power electronic power devices within power conversion circuitry 24.
  • a welding power supply 12 will typically also include an operator interface (not shown) that allows for user selection of welding processes, weld settings, weld parameters, and so forth, such as current and voltage. Such parameters may be conveyed to the arc control circuitry 20, stored in memory, and so forth for use in controlling the welding operation. As also illustrated in FIG. 1 , the digital communication circuitry 30 may allow for communication to remote devices/automation systems 34. Thus, although a manual MIG system is illustrated, the present techniques may be employed with automated (e.g., robotic) systems in which welding may be fully or partially automated based upon the pre-established programming.
  • automated e.g., robotic
  • the wire feeder 14 includes motor/motion control circuitry 36 coupled to the digital communications circuitry 32.
  • the motor/motion control circuitry 36 will include a separate microprocessor or digital signal processor capable of carrying out operations coordinated with the welding power supply as described below.
  • processors will be associated with memory (not separately shown) which may store operational programming, calibration settings, weld settings, operator-input preferences, and so forth. In general, these will include, for example, a wire feed speed, but they may also include wire types, and the like.
  • the motor/motion control circuitry 36 is configured to drive a wire from a spool 36 by commanding operation of a motor 40 coupled to a drive assembly 42.
  • control signals may, for example, take the form of variable voltage signals, and will depend upon the nature of motor 40 and the other components of the system.
  • the wire feeder 14 is also coupled to a gas supply 44 for providing shield and gas for the welding operation.
  • a valve 46 is provided for allowing a flow of gas to be provided to the welding torch, and for interrupting the flow.
  • the valve may also allow for some degree of metering.
  • the valve is controlled by the control circuitry 36.
  • the system of FIG. 1 is synchronized by communication between the digital communications circuitry such that welding operations may be broken into tasks that can be coordinated between the welding system components. That is, whereas in conventional systems operations are typically performed either in an open-loop manner or in a closed-loop manner based upon feedback, at least some of the tasks performed by the components of the welding system as described herein can be performed on a scheduled basis.
  • FIG. 2 represents circuitry tasks performed on a welding system of the type illustrated in FIG. 1 in a synchronized and coordinated manner.
  • a second component begins a first scheduled task as indicated at block 60. Tasks 58 and 60 continue in parallel until time 62. At time 62, the first component carries on a third task 64, while the second component begins a second task 66. At the same time, a third component begins its first task as indicated at block 68.
  • tasks may be scheduled and coordinated to begin and/or end at the same time. However, certain tasks may end earlier that other tasks performed by other components, and the component with the task ending earlier may be instructed to wait until a task is completed by another component. For example, task 58 may be completed prior to task 60, but component 1 may be instructed to wait until completion of task 60 to begin its subsequent task 64.
  • some these tasks may be open-loop operations in which a component is turned off or on, or is commanded to operate at a pre-determined level. Other tasks may be closed-loop, typically based upon feedback of one or more sensed weld parameters as in current welding systems.
  • a command will be received to end the welding operation as indicated at reference numeral 76.
  • this may consist of an operator releasing a welding torch trigger, moving a torch or stick away from a work piece to terminate an arc, or an automated command received from a remote device (e.g., to terminate a weld after reaching a desired location on a work piece).
  • this command is received at time 78, at which the first component begins a scheduled task 80 to begin termination of the welding operation. Following termination of this task, the component performs its final task 82.
  • the second component may begin its last scheduled task at time 86, somewhat after time 78 to begin termination of the welding operation.
  • the third component also begins a task at this stage as indicated by reference numeral 88.
  • These two tasks are illustrated as being completed at time 90 and a final task is then performed by the third component as indicated at reference numeral 92.
  • some or all of these tasks may open-loop or closed-loop based upon sensed welding parameters. Following completion of all tasks, the welding operation is terminated.
  • synchronization of the welding components takes place.
  • the various tasks may be easily coordinated.
  • the command of the tasks may originate in control circuitry of each individual component, or certain components may command operation of others.
  • the present techniques contemplate at least two components having circuitry permitting synchronization and coordinated tasks.
  • some or all of the tasks may be commanded by remote devices, such as that illustrated in FIG. 1 , particularly for automated applications.
  • the tasks performed by the welding system components may be coordinated with tasks performed by other machine systems, such as to begin and end welding operations at particular positions and times based upon location and readiness work pieces, assemblies, and the like on assembly lines and in weld cells.
  • FIG. 3 is a graphical representation of an exemplary welding process 94 of the type summarized in FIG. 2 .
  • FIG. 3 represents the welding process in terms of a magnitude or state of the components along access 96 and a time along access 98.
  • trace 100 represents flow of shield and gas under the control of valving (here "component 1")
  • trace 102 indicates welding wire feed (via control of the wire feed motor and assembly, here “component 2”)
  • trace 104 represents the voltage output of the power supply (via control of the power conversion circuitry, here "component 3").
  • tasks are initiated and completed at particular times for the desired welding operation.
  • the welding operation is initiated by the receipt of a command as described above.
  • a pre-flow of shield and gas is begun by control of the gas valve.
  • This task may be performed open-loop and for a predetermined length of time, followed by a change in the flow rate of the gas as a second task between times t1 and t2.
  • the flow of shield and gas will have reached a steady state level and is not further changed (generally corresponding to the third task 64 illustrated in FIG. 2 ).
  • voltage output of the power supply is significantly increased to anticipate initiation of the welding arc.
  • the voltage reaches a peak and welding wire feed is begun as indicated by trace 102.
  • the welding power supply will continue increasing the wire feed rate, and ultimately an arc will be established during this period.
  • the voltage may be reduced as indicated by trace 104.
  • one or both of these operations may be performed in a closed-loop manner upon detection of currents and/or voltages that indicate the establishment of the welding arc.
  • the wire feed speed and voltage will reach a steady state level, and the welding operation will proceed.
